The TBF Syringe pumps Series has a precisely controlled diaphragm height, making Wearables these products useful in applications where force is applied by a flexible membrane to the sensor, such as infusion pumps. PORTFOLIO The sensor is internally unamplified, providing infinite resolution The TBF Series joins the 1865 Series, FSG Series, FSS Series, and allowing customers to do their own amplification in order to FSS-SMT Series and FSA Series. make use of the maximum resolution of the bare sensor output, leveraging any algorithm needed for the application. The sensor is internally temperature compensated and calibrated. VALUE TO CUSTOMERS Smallest package size in its class (7 mm x 7 mm x 3,89 mm) simplifies placement on crowded PCBs Widest pressure (1 bar to 10 bar 100 kPa to 1 MPa 15 psi to 150 psi) enables choice of optimum pressure range to maximize sensitivity Many different pressure ranges improve resolution and system accuracy Tight accuracy specification of 0.15 %FSS provides user with enhanced accuracy in the application Reliable supply chain Fast response for quotes and samples Designed to Six Sigma standards Manufacturing excellence Supports Lean manufacturing Sensing and Productivity Solutions Basic Force Sensors, TBF Series, Compensated/Unamplified 1 Table 1.

CAUTION PRODUCT SENSING SURFACE DAMAGE The sensing surface of the sensor is composed of a tough silicone gel. Ensure that the sensing surface is not used with media incompatible with silicones. Ensure that the sensing surface does not come into contact with sharp or hard objects. Failure to comply with these instructions may result in product damage. NOTICE In order for the TBF Series sensors to provide a linear and repeatable output, ensure the entire top surface of the gel is exposed to a uniform pressure. The silicone gel allows direct contact with many liquids or the gel may be protected with a thin, compliant membrane. Sensing and Productivity Solutions 2
